Ansible-下载Java JDK-错误：任务：“命令”中指定了多个操作

Question

Ansible：1.9.2（因此使用wget代替get_url）。 Linux CentOS 6.5

运行以下命令并获得以下错误消息：

$ ansible-playbook site.yml ${sudo_user_opts} -i hosts -u builduser --private-key ${DEPLOYER_KEY_FILE} --extra-vars "svr_type=${server_type} deploy_environment=${DEPLOY_ENVIRONMENT} ansible_user=${ANSIBLE_USER}

ERROR: multiple actions specified in task: 'command' and 'Download Java/JDK Versions'

知道我想念的是什么。

我创建的角色“ java”具有default / main.yml：

$ cat roles/java/defaults/main.yml
---
java_versions:
  java7_60:
    version: 1.7.60
    group_path: com/oracle/jdk
    classifier: linux-x64
    ext: tar.gz
    dist_file: "jdk-{{item.value.version }}-{{ item.value.classifier }}-{{ item.value.ext }}"
    dist_url: "{{ artifactory_url }}/{{ item.value.group_path }}/{{ item.value.version }}/{{ dist_file }}"
  java7_67:
    version: 1.7.67
    group_path: com/oracle/jdk
    classifier: linux-x64
    ext: tar.gz
    dist_file: "jdk-{{item.value.version }}-{{ item.value.classifier }}-{{ item.value.ext }}"
    dist_url: "{{ artifactory_url }}/{{ item.value.group_path }}/{{ item.value.version }}/{{ dist_file }}"
  java8_45:
    version: 1.8.45
    group_path: com/oracle/jdk
    classifier: linux-x64
    ext: tar.gz
    dist_file: "jdk-{{item.value.version }}-{{ item.value.classifier }}-{{ item.value.ext }}"
    dist_url: "{{ artifactory_url }}/{{ item.value.group_path }}/{{ item.value.version }}/{{ dist_file }}"

角色some_common的defaults \\ main.yml为：

---
# common vars
artifactory_url: http://artifactory.company.com:9050/virtual-repos

instance_home: "~"
tools_dir: "{{ instance_home }}/tools"
slaves_dir: "{{ instance_home }}/slaves"
build_user: 'builduser'
build_group: 'build'

common_download_dir: "/tmp"

角色内部的任务：java / tasks / main.yml是：

$ cat角色/java/tasks/main.yml

---
- debug: msg="Downloading and installing Java versions - instance_home {{ instance_home }}"

- name: Download Java/JDK Versions
  debug: msg="Java {{ item.key }} is (jdk-{{ item.value.version }}-{{ item.value.classifier }}-{{ item.value.ext }})"
  command: wget -q "{{ item.value.dist_url }}"
    chdir="{{ common_download_dir }}"
    creates="{{ common_download_dir }}/{{ item.value.dist_file }}"
  with_dict: "{{ java_versions }}"

Answer 1

每个任务只能有1个动作。 ansible内置模块debug视为一项操作，因此您必须使其成为自己的单独任务，如下所示：

- debug: msg="Java {{ item.key }} is (jdk-{{ item.value.version }}-{{ item.value.classifier }}-{{ item.value.ext }})"
  with_dict: "{{ java_versions }}"  

- name: Download Java/JDK Versions
  with_dict: "{{ java_versions }}"  
  command: wget -q "{{ item.value.dist_url }}"
    chdir="{{ common_download_dir }}"
    creates="{{ common_download_dir }}/{{ item.value.dist_file }}"
